Abstract
A rotary device includes two rotatable rotors and two stopper mechanisms. The first and second stopper mechanisms restrict relative rotation between the rotors. The first stopper mechanism includes a first protruding member and a first contact surface. The first protruding member includes an elastic outer peripheral part. The first contact surface is disposed at an interval from the first protruding member. The first protruding member contacts the first contact surface when a torsion angle between the rotors reaches a first angle. The second stopper mechanism includes a second protruding member and a second contact surface. The second protruding member includes an outer peripheral part having higher stifffiess than that of the first protruding member. The second contact surface is disposed at an interval from the second protruding member. The second protruding member contacts the second contact surface when the torsion angle reaches a second angle greater than the first angle.
